CAT Data Interpretation Practice Questions & Drills

The nine integers 1 to 9 are written in a 3 × 3 grid, one per cell, so each integer is used exactly once. Rows are numbered 1 (top) to 3 (bottom) and columns 1 (left) to 3 (right). The following conditions hold:

Two cells "share a side" if they are next to each other in the same row or the same column. Cells that touch only at a corner do not share a side. The "four corner cells" are the cells at (Row 1, Column 1), (Row 1, Column 3), (Row 3, Column 1) and (Row 3, Column 3).

The nine whole numbers 1, 2, 3, 4, 5, 6, 7, 8 and 9 are placed in a 3 × 3 grid, one number in each cell, and each number is used exactly once. The rows are numbered Row 1 (top), Row 2 (middle) and Row 3 (bottom). The columns are numbered Column 1 (left), Column 2 (middle) and Column 3 (right). The "corner cells" are the four cells at the corners of the grid. The "centre cell" is the cell in Row 2, Column 2.

The following facts are known:
